BACKGROUND

1. Field of the Invention

The present invention relates generally to healing of wounds and wound-treatment therapies. More particularly, but not by way of limitation, the present invention relates to apparatuses and methods for a multi-conduit connector used in negative pressure wound therapy (NPWT) apparatuses and methods.

2. Background Information

Clinical studies and practice have shown that providing a reduced pressure in proximity to a tissue site augments and accelerates the growth of new tissue at the tissue site. The applications of this phenomenon are numerous, but application of reduced pressure has been particularly successful in treating wounds. This treatment (frequently referred to in the medical community as “negative pressure wound therapy,” “reduced pressure therapy,” or “vacuum therapy”) provides a number of benefits, including faster healing and increased formulation of granulation tissue. Typically, reduced pressure is applied to tissue through a wound insert (e.g., a porous pad or other manifold device).

While NPWT has been highly successful in the promotion of wound closure, healing many wounds previously thought largely untreatable, some difficulty remains. One common component of an NPWT system is a device or structure (e.g., a multi-conduit connector) that connects a canister housing a vacuum, a fluid receptacle, or both to a medical tubeset. The tubeset may be used to deliver negative pressure to the wound site, to remove exudates from the wound site, or both.

While NPWT has been used for some time, multi-conduit connectors can be expensive to manufacture and difficult to install. Often, a user is unable to determine whether a connection has been made between the multi-conduit connector and the canister.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The term “coupled” is defined as connected, although not necessarily directly, and not necessarily mechanically; two items that are “coupled” may be integral with each other. The terms “a” and “an” are defined as one or more unless this disclosure explicitly requires otherwise. The terms “substantially,” “approximately,” and “about” are defined as largely but not necessarily wholly what is specified, as understood by a person of ordinary skill in the art.

The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are open-ended linking verbs. As a result, a method that “comprises,” “has,” “includes” or “contains” one or more steps possesses those one or more steps, but is not limited to possessing only those one or more steps. Likewise, a connector that “comprises,” “has,” “includes” or “contains” one or more elements possesses those one or more elements, but is not limited to possessing only those elements. For example, in a connector that comprises a nipple and a port, the connector includes the specified elements but is not limited to having only those elements. For example, such a connector could also include an annular sleeve.

Further, a device or structure that is configured in a certain way is configured in at least that way, but it can also be configured in other ways than those specifically described.

Embodiments of the multi-conduit connector apparatus depicted may be used in a variety of applications. A non-limiting example of a use for a multi-conduit connector apparatus is in the field of negative pressure wound therapy (NPWT). The connector apparatus can link more than one conduit to a wound dressing and a wound treatment apparatus.

FIG. 1 shows an embodiment of a wound treatment system 10. In the embodiment shown, apparatus 10 comprises a wound-treatment apparatus 14, and a wound dressing 18 coupled to apparatus 14 by a conduit 22. In the embodiment shown, conduit 22 further comprises a conduit 450 and a conduit 460. As shown, dressing 18 is configured to be coupled to (and is shown coupled to) a wound 26 of a patient 30. More particularly, in the embodiment shown, dressing 18 comprises a wound insert 34 and a drape 38. As shown, wound insert 34 is configured to be positioned (and is shown positioned) on wound 26 (e.g., on or adjacent to wound surface 42), and/or drape 38 is configured to be coupled to (and is shown coupled to) skin 46 of the patient adjacent to wound 26 such that drape 38 covers wound insert 34 and wound 26, and forms a space 50 between drape 38 and wound 26 (e.g., wound surface 42).

Apparatus 14 can comprise, for example, a vacuum source configured to be actuatable (and/or actuated) to apply negative pressure (e.g., via conduit 22) to wound dressing 18, a fluid source configured to be actuatable (and/or actuated) to deliver (e.g., via conduit 22) a fluid (for example, an instillation fluid such as a medicinal fluid, antibacterial fluid, or an irrigation fluid) to wound dressing 18. Wound treatment apparatus 14 may further comprise multi-conduit connector apparatus 1000 depicted in FIG. 2 and FIG. 3. System 10 can be implemented and/or actuated and/or coupled to patient 30 in any of various configurations and/or methods similar to those described in the prior art. For example, various wound therapy systems and components are commercially available through and/or from KCI USA, Inc. of San Antonio, Tex., U.S.A., and/or its subsidiary and related companies (collectively, “KCI”).

Conduits 22, 450, 460 can comprise a single lumen conduit (e.g., switched between a vacuum source and/or a fluid source and apparatus 14), or can comprise multiple single-lumen conduits or a multi-lumen conduit such that, for example, fluid can be delivered and/or negative pressure can be applied to wound dressing 18 individually and/or simultaneously. Additionally, conduits 22, 450, 460 can comprise, for example, multiple lumens (e.g., as in a single conduit with a central limit for application of negative pressure and/or fluid delivery and one or more peripheral lumens disposed adjacent or around the central lumen such that the peripheral lumens can be coupled to a pressure sensor to sense and/or detect a pressure or negative pressure between drape 38 and surface 42 (e.g. in space 50), as described in the Hunt and Boynton patents incorporated above.

In the embodiment shown, system 10 further comprises a wound dressing connection pad 54 configured to be coupled (and shown coupled) to conduit 22. One example of a suitable connection pad 54 is the “V.A.C. T.R.A.C.® Pad,” commercially available from KCI. One example of a suitable drape 38 includes the “V.A.C.® Drape” commercially available from KCI.

In some embodiments, engagement tab 430 and sealing ridges 440 are made of a deformable material, including but not limited to rubber or plastic.

Ports 410, 420 are structural elements of multi-conduit housing 400 that are configured to be coupled to nipples 110, 120. Ports 410, 420 are substantially the inverse shape of the corresponding nipples 110, 120. For example, in some embodiments nipples 110, 120 are substantially in the shape of a frustum. In these embodiments, corresponding ports 410, 420 are also in the shape of a frustum. Nipples 110, 120 and ports 410, 420 may also be in the shape of cylinders, cones, prisms, or any other shape about which a seal can be created.

Engagement tab 430 engages clearance shoulders 230 a, 230 b, creating a seal between first port 410 and first annular sleeve 210, and also creating a seal between second port 420 and second annular sleeve 220. Sealing ridges 440 engage first nipple 110, creating a seal between first port 410 and first nipple 110. Sealing ridges 440 also engage second nipple 120, creating a seal between second port 420 and second nipple 120.

In some embodiments, cap sleeve 200 is coupled to canister lid 100 during the manufacturing process. In other embodiments, cap sleeve 200 is installed by a user. In a hospital or clinical setting, a user may engage multi-conduit housing 400 with first nipple 110 and second nipple 120. The user may apply a downward force to multi-conduit housing 400 until engagement tabs 430 passes clearance shoulders 230 a, 230 b and can move no further. In some embodiments, an audible sound may be heard once multi-conduit housing 400 is fully engaged.
